How to identify the quality of mixed ceramic ball bearings? The five-step method teaches you easy identification

With the rapid development of the bearing industry, the application range of hybrid ceramic ball bearings is more and more extensive. In order to help consumers avoid buying inferior products, the following are five simple ways to judge the quality of mixed ceramic ball bearings.

Package clarity

Brands produced by regular manufacturers usually have a dedicated design team responsible for packaging design, and select qualified manufacturers. Therefore, both the lines and colors of the product packaging are very clear and without ambiguity.

Stamp resolution

Each bearing product will be printed on its body brand name, model and other information. Although the font is very small, regular manufacturers usually use steel printing technology to complete the impression before heat treatment, so the font is small but deep into the material and very clear. The fonts of counterfeit products are often blurred, the printing technology is rough, the fonts float on the surface, and even easy to erase by hand.

Running sound

The left hand holds the inner ring of the bearing, the right hand moves the outer ring to make it rotate, and listen to whether there is abnormal noise when the bearing is running. Because the production conditions of most counterfeit products are poor, usually manual operation, it is easy to mix dust, sand and other impurities in the production process, resulting in noise or smooth operation when the bearing rotates.

Surface oil stain

When purchasing imported bearings, it is especially necessary to pay attention to whether there is dirty oil on the surface. Because there is still a certain gap between the domestic rust prevention technology and the international advanced level, thick oil stains may be left when the bearing is treated with rust prevention. The real imported bearings can hardly see obvious traces of anti-rust oil, and careful people can even smell the special anti-rust oil taste.

Chamfer uniformity

The so-called chamfer of the bearing is the junction between the plane and the facade. Counterfeit products, due to production process limitations, are usually not fine enough on these edge treatments, which is a feature that is easy to identify.

With the above five steps, you can be more confident in identifying high-quality hybrid ceramic ball bearings.
